To all whom t may concern:

Be it known that l, Hanni' D. BINns, citizen of the United States, residing `at River Forest, in the county of @ook and u State of Illinois, have invented certain new and uselul Improvements in -a Spray Appliance; and I do hereby declare the "foil-owing 'to be a full, clear, and exact description oli' the invention, 'such Vas will enable others skilled in the art to Which it appe'rt'ains to make and use the same. i

My invention relates to spraying appliances of the general class employed ifor'p'roducing liquid sprays, such as the 'so-called it spray nozzles, atomi'zing nozzles, :and oil burner nozzles, Tn 'one ol its general aspects, my invention aims to yprovide a "slinple, durable and inexpensive yappliance of this kind so arranged that the part which contains the inlet ports `for the'spray-prod'u'ci'ng chamber can readily he withdrawn from the appliance to permit of its being cleaned or for replacing the same.

ln another aspect, inventionaims to provide a spraying appliance having a single-'spray 'producing chai-nicer adapted to he fed interchangeably .i through a number 'of inlet 'port/s, and to provide simple means for shifting the supply of `liquid from :one

to another of its linlet ports, so as to utilize a fresh port in case the previously used one has xbecome clogged or 5to utilize `:a iport of a different size i'f the VsprayingV capacity of the `appliance is to be altered.' ln this connection, my invention also aims to provide 'simple and ehfectiv'e inea-ns for indicatin@ the adjustment thus made.

f* urthermore, iny Iinvention aims to provide `a spraying appliance in which 'the part which containsatleast a` portion of `the spray-producing chamber can readily be withdrawn 'for cleaning-the saine, to lpro vide simple land effective inea-ns for hfoldinv this part in its normal operative position, Vand to utilize .a simple spring for `this' lat'- ter purpose without subjecting the spring to `temperaturey rises 'or `other conditions which `may fexist within the appliance and which might deleteri'ously -la'lfeclt the s ring.

Still further and more "detailed o jects will appear yfrom the following specificanon and nem' 'the accompanying arming inwhich-y F ig. 1 is 'a `'merit-ral and longitudinal seetion through lan appliance einb'xdyi-ng my invention and designed fer-spraying oil'as luelintoaiiurnaceor kiln. '1 i,

ln the embodiment of Figs. "l to f3 vinclufsive vthe appliance 'oli niy invention includes a tubular casing 1 threaded in one otitis rear portions for attachment total pipe through kwhich liquid under' pressurecan `be admitted Ito the bore of the leasing, The

forward lend off this tubular casing Tis closed 'by a head 8 threaded vi-nto thernouth of the casing and having aycontraeted loutlet llthrough which thespray is emitted. Coaxf ial with this outlet, the head "3 is' also 'bored lout "to iit the forward enjd 'of a eyflindricafl 'stem '5, which stein .extends through a stuif- -ing lbox Xat :the rea-r fof the y'appl'iainee land is .pinned to a handle r6 by means et which the-said fstem fcanbe rotated; The forward end of thestem "5 is lo'ored out to :form a lead inte vthe saidehaiiiber near the "rear end or the1aaer-softnatthe liga-'in entering through any .of these' para "win 'have a spirally advancing motiiiiliipartd' 5to the saine ybefore rit -reaches ftl'lhead .gjandfis IJforced out through the spray 'outlet 4i The `ports comprising each r'of desirabl'y 'diametically opposite each other with respect to the common axis of the outlet 4 and the stem 5, so that by suitably rotating the stem, any one pair of ports can be brought simultaneously into alinement with a pair of oppositely disposed grooves 11 which extendlongitudinally of the appliance and which form enlargements for the bore of the stationary head 3. Thus, with the stem 5 in the position lof Figs. 1 and 2, liquid will be admitted from the bore of the casing through the grooves 11 and the ports 8 to .the spray-producing chamber 7, so that with a given pressure of liquid, both the rate at which the spray is emitted and iineness of the latter will depend `on the cross-sectional size of these ports 8. If the other sets of ports (9 and 10) are different in size from the ports 8, the spraying capacity of the appliance can be .correspondingly varied by simply rotating the stem 5 until it brings the ports ofthe desired size into effective alinement withthe grooves 11.

` To'ikeep Ithe forward end of the stem 5 inclosely abutting relation to the head 3, I desirably provide suitableI spring means and vpreferably dispose the spring for this purpose outside of the rearlof the appliance, so that it will not be affected by high temperatures or other conditions existing within orl adjacent to 'they head of the appliance, and also will not be subjected to any action ofthe :liquid with which the appliancemay be used. vFor this purpose, I am here show- `ingfthe Stuliing' box through which the through the stem 5 and which continuously tends to` slide the said stem forward so as to press the tip of the stem against the head 3 of the appliance; Then I am also showing lthe pin 17 as bent down at one end and tapered tojform a pointer 18 moving over a .plate -19 on the rear of the casing, this yplate being marked to indicate the ports or the corresponding spraying capacity which results fromthe corresponding rotational position ofj the stem of the appliance. thus using a rotating stem as the inlet-controlling member of my appliance and providing simple means for indicating the adjustment of the latter, I can enable even an inexperiencedy user to'make thedesired spraying adjustment of the appliance instantly. Likewise, by simply unscrewing thebushingl2 from the casing, I can enable even., an inexperienceduser to make the de-v .fsfiefl Spraying, .adjustment ofthe appliance instantly. Likewise, by simply unscrewing the bushing 12 from the casing, I can removethe stem 5 with this bushing through the rear of the appliance, thus permitting me to remove any scale deposits from the ports or` spraying chamber, or otherwise to clean these parts. Or, if the spraying capacity is to be adjusted to a different range from that afforded by the particular sizes of ports in the stem 5, this stem can easily be exchanged for a similar stem having ports of correspondingly different cross-sections. Or, if the appliance is used for a purpose whereno such adjustment as to spraying capacity is needed, but where the liquid is apt to clog the nozzle, I can employ a stem (like that of Fig, 6) having ports which are all of the same size, turning this stem so as to use one after another of the said ports until they clog, and thus reducing the frequency with which the clogging portion of the nozzle needs to be withdrawn for cleaning the same.

Moreover, it will be noted that both the adjusting of the stem for shifting the operative connection from one set of ports to another and the entire withdrawal of the stem are readily effected from the rear of the appliance, so that it is not necessary for the user to have access to the head end of the appliance for either of these purposes. This makes my appliance particularly advantageous where liquid is to be sprayed into a heated furnace or into a gas cham ber,vneither of which ought to be opened more than vis absolutely necessary. For eX- ample, in the embodiment of Fig. 1, the manipulating is allJ done from the rear of the appliance or outside of the inclosing wall 20 through which the appliance eX- tends.

However, while I have heretofore described my 'invention in a desirable embodiment and have spoken of certain uses of the same, I do not wish to be limited to such uses, nor to the details of construction and arrangement thus disclosed, it being obvious that the same might be modified in many ways without departing from the spirit of my invention or from the appended claims. For example, Fig. 4 shows the forward end of a spraying appliance in which the sprayproducing chamber consists partly of a bore Itl in the head 3 of the appliance and partly of a corresponding bore 7b in the forward end of the stem 5, and in which the inlet ports consist of slots 20 in the forward end of the stem. In this case, these slots are all of the same cross-section, so that the amount of liquid supplied through any pair of them will be the same with a given pres` sure, thus adapting the construction to conditions where it is particularly important to overcome a clogging of the appliance without taking the same outef serviced I claim as my invention l.
